[Gc] RE: can't for daemon problem with gcc/gcj compiled program

It looks like the thr_create call in solaris_threads.c is failing.  A
bit of debugging to determine the errno value would be useful.

Is this really being linked against the thread library?  Or is it just
picking up a dummy thr_create() that always fails?
